IMPROVEMENT III seno-rLAIIrINeV MAGHINE.

@In Ssttrmle tratta tu trillen tettett hadnt mit attingere rf tige anniT0 ALL WHOMIT'MAY GNGERN: I Be it-known that I,-FnEDnRIcK'W. TIL'roN, ofMoline, iaithe county of Rock Island, in the State of Illinois, haveinvented certainnew and useful Improvements in :See'd-Planting Machines;and I do herebydeclare that the following is a full and exactdescription thereof. 4 p

. I will first describe what I consider the ,best means of carrying'outmy invention, and will afterwards designate what I believe to be newtherein. -The accompanying drawings form a part of this specicatiOn,andrepresent the novel features of my invention, with s'o muchof-theother parts as is necessary to show their relatio'n thereto.

Figure 1 is a transverse section on the line X X, in fig. 2, showinglthe seed-cells and lower portion of the hopper of my `improved`seeding-machine.

I Figure 2 is a plan view `of both sections of'the sleeve and.seed-cells, and showing, in red lines, the hub of one of thecarrying-wheels.

Figure 3 isa longitudinal section of the outer end of the axle, showinga portion of the adjusting-screw v and nut that holds .the wheel inposition. This figure shows very clearly thev arrangement ofthescrew-bolt which adjusts the sizeof the seed-cups.

t Similar letters of reference indicate corresponding parts in.allthe'gnres. A is a tubularA shaft, of iron, which forms theaxle of Imymachine, and on .which 'the carrying-wheels'are secured by means ofcap-nuts B. A" is a shaft, of wood or metal, placed inside of the axleA, and adapted to be moved in alongitudinal' direction relatively to theaxle. C is a square-headed screw-holt, which passes through the cap-nutB, and is-tapped into the end of the shaft vThe outerendof thisholt C ismade square, as seen atc, and upon the part e is rmly secured Va squarehead, c1, hywhieh the screw is operatedi The bolt C is prevented ,frombeing moved endwise in either direction rela-tively Ato thenut Bvbymeans of the s'houlderc2 upon the' inside, and Vthe head c1 upon theoutside of the cap-nut B, and thus' it will he seen that the shaft A maybe movedendwise in either direction relatively to the axle A,-lv byturning-theiscreweolt G, without depending on a spring to move it ineither direction. D is a hoop or sleeve 'firmly secured by screws or'otherwise upon the hollow axle A. E is a. sleeve fitted loosely 'uponthe axle A, and firmly secured tothe enclosed part A by means of screwsI, which pass through longitudinal slots O-in the axle A. The adjacentends ofthe sleeves D and E are provided with longfingers d and e, andlong notches all and e', so arrangedv that .the lingers d upon thevsleeve D it into notches e', ofcorresponding size, in the sleeve E, andthe ngers eL upon the sleeve E, fit into corresponding notches ci in thesleeve D. As the `sleeve E is moved away from the sleeve D,'spaees` areleft which serve as seed-cups for receiving and distributing the seed.v- The capacityof these cups may be' increased or diminished to anydesired extent `hy moving the loose sleeve E from or towards the fixedsleeve D, by means of the adjusting-screw- C and .the connecting-shaftA. G is the lower part of a hopper,.

which receives the seed to be sown. Its under side is holle-wed our. soas to it uponthe uppercylindrieal sur* face of the sleeves DE, withsuiiicient tightness to upret'ent'the escape` of seed. A flexibletongue. or cut-oft,`

g, of rubber, leather, or other ilexible material, in the form of a.sheet, is secured in the lower partof the hopper by ineans of a narrowsheet of metal, g1, and compressing-screws g tapped into the side of thehopper.l As the axle revolves, the lower edge of this ilexiblecut-.oil'V g stands closelyin contact with the cylindrical surface ofthe crowns `D and prevents the seed from being crushed or injuredbetween the lower side .of thehopper and the edges ofthe seed-cups. l His a clutch rmly secured upon the axle A, Ktis a corresponding clutch,rmly secured to the inner end of the hub L of one 'of thecarrying-wheels. When the carrying-wheel moves forward, the clutchKlecks into the clutch H, and thus puts thesowing-apparatus intooperation,-

In moving from one ield to another, .or when, from any-reason, it isdesirable to move the machine forward without operating thesowing-apparatus, the' clutchl is thrown out of contact with the clutchH, by means of a lever not represented,'or any 'well-known de vice,which shall move the hub L outward toward the nut B, by taking hold inthe groove K. I

Although I haveshown and described but one set ofsleeves,'D E, itis'evident that I may have any number of sleeves D secured upon the axleA, andv any number of sleeves E secured to the shaft A', so that .theycan all he moved simultaneously by the adjustment of the singlescrew=bolt C.

My machine is capable of sowing in drills, or, by removing those partewhich belong particularly to a.

drilling-machine and substituting therefor a'deecting-board for properlydistributing the seed, can be used for broadcast sowing` as well.

Having now fully described my invention, what I claim as new inseed-planting machines, and desire to secure by Letters Patent, is asfollows:

`I claim the adjustng-screw'bolt C, having a recess or groove, c3, asrepresented, in` combination with the I section-or crown' D, xed on theouter shaft A, and Section or crown E, having an inward connection tothe interior shaft A", all arranged substantially in themanner and forthe 'purposes herein set forth.

In testimonyvwhercof, I hereunto set niy hand in presence of twosubscribing witnesses.
